UNITED STATES PATENT OFFICE.

DANIEL A. KILMER, OF HOWES GAVE, NEW YORK.

WIRE-TWISTER.

SPECIFICATION forming part of Letters Patent No. 228,905, dated June 15, 1880.

Application filed April 5, 1880.

To all whom it may concern Be it known that I, DANIEL A. KILMER, of Howes Cave, in the county of Schoharie and State of New York, have invented certain new and useful Improvements in \Vire-Twisters; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, makin g a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a perspective of my wire-twister. Fig. 2 is a detail viewof the same, and Fig. 3 is a view of a modification.

The nature of my invention relates to wiretwisting machines. 7

The object of my invention is to construct a wire-twister which shall be reversible, and which shall also admit of the wire beingthrown off at any desired stage in the operation of the machine.

The bed or table A is mounted upon suitable supporting-legs, and is provided with the usual griping-jaws B, which are used for holding the wires which are to be twisted.

0 C are two treadles, which are connected with the shaft D by cords D. These cords are secured to drums or spools upon the shaft D, and are wound thereon, so that the alternate vibrations of the treadles will cause reverse movements of the shaft. The twisterE is arranged upon one end of this shaft, and is in line with the space between the gripingjaws.

(No model.)

In order to bring either tread to a stop at a certain period, and thus stop the motion of the shaft and twister at the same time, I provide a block, H, having recesses I, into which the treadles pass when they are depressed. Pins K are passed through the block, and these pins may be raised or lowered in the block, so as to limit the downward movement of either treadle, thus regulating the position at which the twister stops.

The shaft is mounted in bearings which are secured to the table, these being of any suitable construction.

The treadles are hinged to a cross-rod, L, and are arranged in a convenient position for the operator.

The shank of the hook or twister is held in the end of the shaft by a set-screw, whereby when the hook or twister becomes worn it may be removed and a new hook substituted or the old hook refitted.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

In a wire-twisting machine, the rotary shaft D, with a hook, E, fitted in one of its ends, in combination with the cords D D, the treadles O, and the stop-block H, with recesses I and pins K, the said cords being connected with pulleys upon the shaft and with the treadles, and the stop-block H being provided with holes, through which the pins are passed, all substantially in the manner and for the purposes speoified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
